BUILDING CONSTRUCTION.

Application led November 15, 1926. Serial No. 148,441.

This invention relates to building constructions and more particularly to a method of fastening and re-enforcing sheathing.

In view of the increase in the cost of lumber and the steadily growing demand for insulationof homes, composition boards are being used as a substitute for wood sheathing. The composition boards now on the market are made of waste sugar cane, wood liber, corn stalks and other waste vegetable matter. In addition, boards made of mineral compositions and consisting of combinations of gypsum, magnesite and other may terials provided with paper facings or coverings are being used for this purpose. These boards develop certain defects which, to some extent, defeat the purpose of the sheathing through the loosening of the nails by which they are secured to the frame of the building. The object of the present invention is to provide means for stiifening the Y structure with a metal re-enforcing and and provided with flanges extndin reducing the number of nail holes through the boards. i

In carrying out the invention, I provide a strip preferably formed of metal adapted to fit over the adjacent edges of two boards over the outer surface of one of the boar s and the inner surface of the other. Either one or both flanges may be nailed to the frame work. The nails in the iiangeat the rear ot the boards do not extend through the boards and any nails driven through the other flange are re-enforced by it and prevented from loosening by the metal of the flange.

The web of' the strip may, or may not, be at right angles to the flanges, depending on which it is to be used. The cross section of the strip may be varied to accommodate boards of different types and I have shown several ydifferent forms of the strip in the accompanying drawings.

Referring to the drawings- Fig. 1 is a front elevation of a portion of a wall showing the invention applied;

Fig. l0 is a similar view of a strip used in connection with boards having, curved edges, and, n

Fig. l1 is a similar view of a strip used in connection with boards having tongues and grooves in their meeting edges.

Referring to the drawings, the reference numeral 1 designates the sections of the composition board which may be of any of the various types yof board manufactured and sold as a substitute for sheathing. The sections of the board mayibe of any desired width and length. These boards are generally made four feet in width and of various i lengths. rIn applying the sheathing to a building, it is nalled to the vertical studding, 2, which studding is placed at predetermined distances from each other.- In emplo ing the re-enforcing and connecting stripy orming the subject matter of the present invention a horizontal row of the sheath ing strips are rst applied and before the application of the next row, a connecting strip is placed along the upper edgev of thev boards and thealower row. This connecting strip consists'of a web, 2', adapted to be arranged over the upper edge of the board and provided `with flanges 3 and 4. The front ange, 3, is a depending ange and extends over a portion of the outer face of the lower strip adjacent its upper edge. They rear flange, 4,- extends upwardly in contact with the face of the studding and is secured thereto by nails,. 5, driven through the flange.l As the composition -boards are frequently made with their edges at an angle other than a right angle to the face, the web may be -arranged at a corresponding angle as shown in Fig. 2 of the drawings to t snu ly over the edge of the boa'rd.

1 In igs. 3 and 4 of the drawings, I have shown two forms of the strip in which the angle of the web to the flange varies to correspond to the angle of the edge of the board with which the strip is used in each instance. As shown in these views, the boards may be secured to the studding entirely by the nails, 5, passing through the rear flange, 4, so that no nails pass through the board. When the rear flange is secured to the studding in this manner, the engagement of the flange, 3, with the front of a board is sufficient to re` tain it in position and the lower edge of the upper board is retained in position by the arrangement of its lower portion within the strip.

It is sometimes advisable, however, to rail the lower flange to the studding as well as the upper flange and in this instance, a nail, 6, may be driven through the lower flange and the board as shown in Figs. 2 and 5. I have found, however, that the nail passing through the met-al flange does not tend to loosen as heretofore when passed directly through the composition board. Due to the presence of the metal flange, moisture is prevented from entering the nail hole and causing it to enlarge. In Fig. 5 of the drawings, I have not only shown the nail passing through the lower flange, but have also shown the web at a more acute angle to the flanges.

In the construction of a building the reenforcing strips are arranged horizontally and I also find it advantageous to secure the boards to the studding by vertical rows of nails. Nails, 7, are driven through the board into the studding' in vertical rows as indicated in Fig. 1 of the drawings. In connection with these nails, I preferably employ metal washers, 8. When the nails are driven f into the board, the central portion of the washer is forced inwardly as at 9 causing the edges'of the washer to tightly engage the surface of the board and prevent water from getting beneath the washer and entering the nail hole.

In Fig. 8 of the drawings, I have shown a strip in which the web, 27, is substantially V shaped in cross section. This strip is adapted to be used with a lower board having a V shaped projection adapted to be received in a. V shaped recess on the lower edge of the upper board to form a lap joint. The web fits snugly over the edges of the boards and does not interfere with the formation of the lap joint.

The form of the invention shown in Fig. 9 of the drawings is adapted to be used when the V shaped recess is on the upper edge of the lower board and the projection on the lower edge of the upper board.

Fig. 10 shows a somewhat similar construction in which the strip is adapted to be used with boards having curved edges, one of which is concave and the other of which is convex. In this form the web is similarly curved.

In the form of the invention shown in Fig. ll of the drawings, the web is substantially at right angles to the flanges, 3 and 4, but is provided with a centrally disposed rounded portion, lO. This form of strip is adapted to be used with boards having tongues and grooves on their meeting edges and the portion, l0, is shaped to correspond with the shape of the tongues and grooves. The metal strips may also be arranged along the vertical edges of the boards and the vertical rows of nails, 7, driven through the flanges, 3 or 4, thus, disposing with the metal washers, 8.

The metal re-enforcing strips may be of any gauge and may be provided with series of nail holes at regular intervals. I have found that when 28-3() gauge galvanized iron is employed the nails may be driven through the strip and it is unnecessary to punch the nail holes in the strip prior to its application.
